Feed is the first and foremost factor that affects the growth of aquatic animals. Manufactured feeds are an important part of modern commercial aquaculture, providing the balanced nutrition needed to fish. The feeds, in the form of granules or pellets, provide the nutrition in a stable and concentrated form, enabling the fish to feed efficiently and grow to their full potential. Modern fish feeds are made by grinding and mixing together ingredients such as fishmeal, vegetable proteins and binding agents such as wheat.
